A development environment which includes a webserver, a proxysql instance and an RDS instance for testing and experimentation with ProxySQL.
First, Terraform is used to:
- Generate a password for the RDS instance and store it in AWS secrets manager
- Create 2 EC2 instances
- Create an RDS instance including 1 read replica, using the password from secrets manager
Then, Ansible is used to:
- Configure one EC2 instance as a webserver
- Configure the other EC2 instance as a ProxySQL instance
- Set up some test data on the RDS instance
- AWS access key and secret with permission to create EC2 instances, RDS instances and read/write to AWS Secrets Manager
terraform apply
- Update webserver_aws_ec2.yml with your AWS access key and secret, so it can configure the webserver EC2 instance based on its tag of 'webserver'
- Update proxysql_aws_ec2.yml with your AWS access key and secret, so it can configure the webserver EC2 instance based on its tag of 'proxysql'
Run the Ansible playbook to configure the RDS instance, it will create a database and a user:
ansible-playbook rds.yml
Run the Ansible playbook to configure the webserver, it will install Apache, PHP and adminer:
ansible-playbook -i webserver_aws_ec2.yml webserver.yml
Run the Ansible playbook to configure the proxysql instance, it will add a hostgroup, host and user:
ansible-playbook -i proxysql_aws_ec2.yml proxysql.yml
Once the above have been run, you can connect to the database via the proxy address, using Adminer on the webserver at https://{webserver_public_ip}/adminer.php
